How do I register hot key for volume keys on WM6.5?

Question

Hi,

RegisterHotKey() always returns false when I try to register Volume keys as hot keys.  Both volume keys exist on my Windows Mobile 6.5 device.

bool ret = RegisterHotKey(AfxGetMainWnd()->GetSafeHwnd(), 35, 0, VK_F7);

I try both VK_F7 and VK_TVOLUMEDOWN, but still returns false.

But when I try to register hot key for key 9, it returns true.

bool ret1 = RegisterHotKey(AfxGetMainWnd()->GetSafeHwnd(), 25, 0, 0x39);

Answer 1

Hello,

How about set VK_TVOLUMEUP with hex value
 bool ret = RegisterHotKey(AfxGetMainWnd()->GetSafeHwnd(), 35, 0, 0x75);
Or 0x76

Best regards,
Jesse

Answer 2

Hi Jesse, thanks for the reply.  I tried both hex values and they don't seem to work because both return back as false. 

Answer 3

What's the value of GetLastError() function.
